Description

Technical Field

[0001] The utility model relates to the technical field of bags, in particular to a dust bag installation structure in a bag dust collector. Background Art

[0002] A bag filter is a dry dust filter suitable for capturing fine, dry, non-fibrous dust. Made of textile filter cloth or non-woven felt, the filter bags utilize the filtration properties of the fabric to filter dust-laden air. When dust-laden air enters the bag filter, large, high-density dust particles settle due to gravity and fall into the hopper. Finer dust particles are retained as they pass through the filter material, resulting in purification.

[0003] However, the installation method of the cloth bag of traditional vacuum cleaners is as follows: a ring-shaped spring sheet is embedded in the upper end of the cloth bag. During installation, the spring sheet is pressed to deform it, and the cloth bag is installed on the flower plate. Then the spring sheet is released and the cloth bag is reset to make the cloth bag and the flower plate collide with each other. However, in actual use, the cloth bag becomes loose as the use time increases, resulting in reduced sealing and dust leakage. For this reason, the present application proposes a dust bag installation structure in a bag dust collector. Utility Model Content

[0007] Cloth bag mounting structure; the cloth bag mounting structure includes a connecting ring fixed to the upper end of the cloth bag body, the connecting ring passes through the cloth bag mounting hole and is sealed therewith, a limiting ring is fixed to the upper end of the connecting ring, the bottom of the limiting ring is against the upper end of the flower plate, the upper end of the flower plate is provided with an annular arc groove, the bottom of the limiting ring is fixed with a rubber ring, the rubber ring is located in the annular arc groove and is squeezed and deformed.

[0008] Furthermore, a rubber ring is fixed to the outer wall of the connecting ring, and the outer wall of the rubber ring abuts against the inner wall of the cloth bag mounting hole.

[0009] Furthermore, the outer diameter of the rubber ring is larger than the inner diameter of the cloth bag mounting hole, and the outer wall of the bottom of the rubber ring is provided with a conical annular inclined surface.

[0010] Furthermore, it also includes four pressing mechanisms for pressing the limiting ring, and the four pressing mechanisms are distributed in a ring array outside the limiting ring.

[0011] Furthermore, the clamping mechanism includes a shaft rotatably mounted on the flower plate, a pressure block is fixed on the shaft, and an anti-slip pad is fixed to the bottom of the pressure block.

[0019] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-Figure 3 As shown, the embodiment of the present invention proposes a dust bag installation structure in a bag dust collector, comprising:

[0021] Flower plate 1, flower plate 1 is provided with a cloth bag installation hole 9, and the cloth bag installation hole 9 is installed through the cloth bag body 2;

[0022] Cloth bag mounting structure; the cloth bag mounting structure includes a connecting ring 4 fixed to the upper end of the cloth bag body 2, the connecting ring 4 passes through the cloth bag mounting hole 9 and is sealed therewith, a rubber ring 8 is fixed to the outer wall of the connecting ring 4, the outer wall of the rubber ring 8 is against the inner wall of the cloth bag mounting hole 9, the outer diameter of the rubber ring 8 is larger than the inner diameter of the cloth bag mounting hole 9, and the bottom outer wall of the rubber ring 8 is provided with a tapered annular inclined surface, the outer diameter of the lower end of the annular inclined surface is smaller than the inner diameter of the cloth bag mounting hole 9, so that when the connecting ring 4 and the rubber ring 8 are installed in the cloth bag mounting hole 9, the rubber ring 8 can pass through the cloth bag mounting hole 9, and after installation, the rubber ring 8 is against the inner wall of the cloth bag mounting hole 9, and the rubber ring 8 is squeezed and against the inner wall of the cloth bag mounting hole 9, so that the sealing between the connecting ring 4 and the cloth bag mounting hole 9 can be ensured.

[0023] The upper end of the connecting ring 4 is fixed with a limiting ring 3, and the bottom of the limiting ring 3 is against the upper end of the flower plate 1. The upper end of the flower plate 1 is provided with an annular arc groove 6, and the bottom of the limiting ring 3 is fixed with a rubber ring 7. The rubber ring 7 is located in the annular arc groove 6 and is squeezed and deformed. Through the cooperation of the rubber ring 7 and the annular arc groove 6, the sealing between the limiting ring 3 and the flower plate 1 can be increased. In this way, through the double sealing setting, dust leakage during dust removal can be effectively avoided.

[0024] Since the rubber ring 7 is located in the arc groove 6 and the limit ring 3 is loose, four clamping mechanisms 5 are also included to clamp the limit ring 3. The four clamping mechanisms 5 are distributed in a ring array on the outside of the limit ring 3. The clamping mechanism 5 includes a shaft 12 rotatably mounted on the flower plate 1, and a pressure block 10 is fixed on the shaft 12. An anti-slip pad 11 is fixed to the bottom of the pressure block 10. The rotation of the shaft 12 drives the pressure block 10 to rotate to the top of the limit ring 3, and the anti-slip pad 11 is against the upper end of the limit ring 3. The anti-slip pad 11 is a rubber pad. During installation, the shaft 12 is installed so that it is not opposite to the limit ring 3, so that there will be no interference when installing the cloth bag body 2 and the limit ring 3.

[0025] After the installation is completed, the staff manually rotates the pressure block 10, and the rotation of the pressure block 10 drives the anti-slip pad 11 to rotate, so that the anti-slip pad 11 is located at the upper end of the limit ring 3. At this time, the anti-slip pad 11 is deformed, and the limit ring 3 is pressed tightly by friction. When rotating, the limit ring 3 can be pressed down to deform the rubber ring 7, which will not hinder the rotation of the anti-slip pad 11 and the pressure block 10. In this way, the limit ring 3 can be pressed and locked and will not loosen. Finally, the keel is placed in the cloth bag body 2, and the upper end of the keel is placed on the limit ring 3.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
